APPARQTUS FOR FEEDING PAPER '10 PRINTING-PRESSES, &c. 'l I Specification of Letters Patent.

Application filed June 18, 1900. Serial No. 20,682.

To all whom it may concern:

Be 1t known that I, Invnzo I. STONE, c1t1- zen of the United States, residing at Chi-' cago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Apparatus for Feeding Paper to Printing-Presses, &c., of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forminga part of this specification.

My invention relates to apparatus for feeding paper to printing presses, etc., my

object being to'provide a. suitable device adapted to hold a plurality of rolls of paper or like material adapted to be fed to printinggpresses or other mechanism, the sup port being associated with a feeding device whereby the rolls may be successively brought into engagement with the feeding device to feed the paper therefrom.

I have illustrated my invention in the accompanying drawings in which Figure 1 is a view of one end of the .device of my invention showing the means employed for rotating the frame. Fig. 2 is a side view of the rotating device. Fig. 3 is a view of the other end of the device of my invention showing the rolls of paper in position. Fig. 4: is a view of the belts employed to feed the paper to the press. Fig. .3 is a detail view showing one method of securing the rolls of paper when paper spools are used. Fig. 6 is a. side view of my invention showing the reel partly turned in the process of changin the feed from one roll to the other. Figs .v 8, and 9 are diagrams showing the working of the device of my invention. Figs. 10 and 11 are views of the switch controlling the motor. Fig. 12 is a diagram of the circuit connections thereof. Fig. 13 is a view of an automatic attachment for this switch. Fig. 14 is a detail view of the springs in Fig. 13. I

Like letters refer to like parts in the several figures.

An axle or shaft a is mounted in bearings b on the frame work 6. Upon the axle a is carried a frame 0 consisting of a plurality of arms, (Z, of equal length, each carrying at its extremitya bearing 0' for the shaft 0 which carries the paper roll 0. The frame 0 is rotated about the axle a by means of a worm a which acts upon the periphery of a worm wheel a, which is keyed or other- .tates upon an axle f wise fixed to the axle a. The worm a may be turned by either the small adjustment of the rolls, or by means of a motor a acting by means of the pinion ahdnvmgthe gear wheel a, in order tobring another roll of paper into position to be run nto the press, after the roll previously in positionhas been exhausted. In the construction illustrated the rolls of paper are fastened to the axle c by means of a device like that shown in Fig. 5, which consists of a continuation c of the shaft 0' which has a slot 0 cut therein. In this slot 18 pivoted, at 0 a bar 0 which has two or more teeth a, at its outer extremity. A bolt 0 is adapted to move the bar 0 so that the teeth 0 will engage the roll of paper, and fasten it in position. Normally the spring 0 keeps the bar 0 in such a position that the teeth 0 are withdrawn into the slot. IVhen it is desired to fasten a roll into place, the extension 0 is pushed into the bore of the roll 6. The bolt 0 is then turned to swing the bar 0 into such a position that the teeth a will engage the inside of the roll and hold the paper firm. There are two shafts or spindles c for each roll. These spindles are in alinement and adapted to grip the bore of the roll when the roll is in position.

The belt f of leather or other suitable material runs on the wheels f f, and passes over a portion of the periphery of the roll 6 from which the paper is passing to press. The weight of the belt and its frame is sufficient to produce enough friction between the belt and the paper for the roll to be rostamens. 12, 1915.

hand wheel a for tated by the revolution of the belt and the paper thereon fed into the press. One of the wheels f rotates upon an axle ,7 which is suspended from the ceiling or other partition by a hanger f. The other wheel f rowhich is carried by the lower end of the frame 7, which depends from the axle i The frame F is so pivoted that as the amount of paper on the roll decreases the frame descends, thus lesseningv the weight upon the roll in proportion as the amount of paper decreases, thus providing a substantially constant strain or tension upon the paper, which would not be obtained were there a constant weight upon the top of the roll.. When it is desired to raise the belt 7 from in contact with the roll e the hook f may be connected to the bar f and the chain f running over the pulley f tightened by admitting compressed air'into the chamber g, by means of the stop-cock 9 Power is supplied to the wheels f from any convenient source and the belts are driven at the proper speed to properly feed the paper to the press.

In supplying the rolls of paper to the ma- .chine they are placed upon a truck m which rides upon' a track an by means of wheels m. Part of this track runs upon a platform n which moves upon wheels n. The truck containing a roll of paper is pushed upon the platform 12. and the platform n pushed out until the center 0 is in the circle formed by the axis 0 in its rotation. The frame 0 is then rotated by means of the motor a until the axis 0 is in alinement with the bore 0 The roll c is then fastened in position as described, the, frame 0 rotated, and another roll put in. It will be noted that the truck which is used to carry the .rolls of paper to 'theframe is in fact in two parts which may be called trucks. The paper is received upon the platform or truck m, which has wheels running on rails on the part or truck I 07., while the truck n has wheels running on rails at right angles to the rails carried by it. When one roll has been exhausted the speed of the press is slackened somewhat. The flaps e on the next roll have been gummed on the outside and retained in position close to the roll by a little adhesive placed underneath them. The frame 0 is now rotated to the position shown in Fig.

8, where the second roll comes in contact with the belt 7; This contact causes the roll to rotate and the flaps e passing between the belt f and the roll e are thereby gummed to the paper running to press from the first roll. The paper on the first roll is then severed as shown at the dotted lines andthe frame 0 rotated into position shown in Fig.

When the device is in operation, the pressure between the belt 7 and the roll, and hence the feed, may be varied and regulated by moving the roll with relation to the belt so as to change the point of contact and bring it nearer to or farther from the pulley 1 about which the belt f travels. movement is obtained in any degree by moving the frame upon which the rolls are mounted. Stating this in another way, this This movement varies the position ofthe point of contact with relation to the point of support of the belt, and I have found that by this means I am able to adjustv the feed to meet the conditions presented. As the material on the roll is fed forward and the roll decreases in diameter, it is very beneficial to decrease the pressure between the belt and the material, and this result is automatically produced in the device herein shown and is in fact responsive to the variation in the diameter of the roll.

In order to obtain as near as possible the exact amount of rotation for the frame 0, I provide the device shown particularly in Fig. 13. A plate of fiber 72 is screwed onto the end of the axle a. Into this plate is fitted the metal ring 1) having the outwardly extending arms p Two segments of fiber p p are screwed upon the bearing 6. To these segments are attached ,two copper springs 32* p. To these springs are attached the brushes 7) 72 one of which rests upon the ring 1, and the other upon the segments p of the fiber plate p.v The spring is made adjustable by fastening it movably upon the run. way

The copper strips 8 of the switch 8 are adapted to fit into the terminals 8 in such a way that by connecting hne pair the motor a will be run in one direction, and reversed by connecting the other pair. The magnets s are connected in series with the motor a so that when the motor has been started the magnets will be energized and hold the handle 5, which is of magnetic material against the armatures 8 8 against the tension of the spring 8 One end of the windings on the magnetsv s is connected with the spring 11 and the other end with the spring p.

When it is desired to rotate the frame 0,

to place in a new roll of paper, the switch a is moved to start the motor (1,, which rotates the frame 0. This also energizes the magnet 8 which holds the switch in position. As the frame rotates, the plate 79 and the ring 1) revolve also until one; of the arms 1) strikes the brush p of the spring 1), thus short circuiting the magnet 8 The spring 8 now forces the handle out of contact with the terminals 8', and allows it to drop to its normal position, thus breaking the circuit through the motor a In practice, the spring 1) isadjusted so that'the magnet will be short circuited when the frame is in the position shown in Fig. 8. The pasting and cutting is then done, and the switch manipulated by hand to rotate the frame to the position shown in Fig. 9.

As illustrated in Fig. 1 the point of suspension of the feeding belt is in a vertical plane which passes through the roll upon which the belt is' operated.

It will be noted that prior to pasting the Web of the new roll to the web of the old roll the two rolls are brought to substantially the same speed, and then while the webs are traveling at substantially the same speed, they are pasted together. In' the present instance it will be noted that this speed must necessarily be the same, because of the fact that the same belt F engages both webs and causes them to travel with it. It is of course evident that any othersuitable means for this purpose may be used. l
